A quote fronm the article "Thanks to all for the insightful comments. The oil cooler was the crux of this build. Initially I was committed to a minimal cooler using a Spurgin heat exchanger but could not achieve the lean effect I wanted. My brotherís encouragement (at times dangerous but always fun) pushed me to do the final build without it. Before I pulled the trigger, I talked with Bill Himmelsbach (http://www.eurosports.net/staf...
about his scrambler builds. Bill knows these bikes inside and out and assured me that the oil cooler loop is independent from the lubrication circuit and that capping the feed does not stress the pump. He runs a big bore kit and mild cams without a cooler. After 3000 miles (including a track day and a flogging by the moto journalist Alan Cathcart), Bill disassembled the engine and saw no unusual wear. Furthermore, Bill said there was no color change around the piston wrist pin, an area that turns a telltale gold tint with overheating. That said, I offer the Spurgin cooler set-up as a no cost option. I do not run one on the development mule, but plan to install it when the bike is prepared for my Delhi to Leh-Ladakh ride next spring.

I have been using Bill Gately's oil coolers for a couple of years with out incident. http://www.bonnevilleperformance.com/
No connection with any of these suppliers other than a customer of Bill Gately
Thanks Skid, so I have something to read and study
There aren't strangers, only friends you haven't ever met.
